FERTILIZATION or Satvra By HUMBLE Bees. — Mr. Meehan's state- 
observations on the same subject, that I cannot allow them to pass un- 
challenged. r. Meehan affirms that the humble bee does not enter the 
corolla of the Salvia to obtain the honey, but **bores a hole on the out- 
side” for that purpose. He says, after describing the "E of the 
flower — ** The principle is perfect. But no insect is seen to enter.” This 
statement is certainly not in accordance with facts. I have sida and 
again observed the conduct of the humble bee on the Salvia; and I affirm 
that a large majority of the bees do enter the corolla, and that the anthers 
rest on the back of the insect exactly in the way that Mr. Meehan says 
they ought to rest. It is true that some of the bees do cut the tube of 
the corolla to get the honey. This, however, is only done by those bees 
which are too large to get into the flower. — E. H. T., —Q Delaware
